Rehabilitation of a lost immature permanent central incisor due to avulsion injury with a modified essix retainer: A case report

The type of injury in which a tooth is completely displaced from its alveolar socket following trauma is called avulsion. Traumatic injuries to permanent incisors are quite common during childhood, with 0.5–16% of children aged 7 to 10 experiencing permanent incisor avulsion. Tooth avulsion usually occurs due to road traffic accidents, falls, and other physical impacts. It can also happen during sports in schools or as a result of physical violence. Permanent incisors are important not only for aesthetics but also for phonetics, mastication, and the psychological health of young patients. Traumatic dental injuries should be thoroughly evaluated and managed by clinicians. An appropriate emergency intervention and treatment plan are crucial for a good prognosis. However, due to various reasons, this condition can result in tooth loss. It is essential to preserve the spaces of avulsed teeth with space maintainers until the patient reaches the appropriate age for permanent treatment. The aim of this study is to improve the quality of life of an 8 year old pediatric patient in the mixed dentition period, whose upper right permanent central incisor tooth was avulsed, by providing temporary oral rehabilitation with a modified essix appliance and to offer a qualified treatment alternative to the patient.
